 Another version of that story says that the officers who worked in the Tenderloin received a "hazard pay" bonus for working in such a violent area, and thus were able to afford the good cut of meat.Yet another story, also likely apocryphal, is that the name is a reference to the "loins" of prostitutes.The Tenderloin borders the Mission/Market Street corridor, which follows the Spaniards' El Camino Real, which in turn traced an ancient north–south Indian trail.
